Energy Consumption Analysis of AODV-UI Hybrid Routing Protocol under Various Mobility Models

December 26, 2011

This is our first draft joint research paper that we submitted to Networking 2012, The International Conference on Networking. This joint research is involved 2 universities, Universitas Indonesia and Universite de Haute Alsace-France. We hope that this paper could represent both universities in the conference.

Abstract – Mobile ad hoc networks (Manets) are characterized by mobile with portable and limited power sources. For more than one decade, Ad hoc On-demand Distance Vector (AODV) routing protocol becomes attention and research focus on MANET widely. A lot of protocols proposed to improve and optimize AODV performance. Yet, many of those do not consider the needs of node accessing Internet via infrastructure network. In this paper, we proposed a optimize hybrid routing protocol based on AODV routing protocol, called AODV-UI. Our proposed protocol combines two mechanism such as gateway mode and reverse route mechanism with the aim to improve the performance of the hybrid protocol. We performed some evaluation of energy consumption calculation in our proposed hybrid protocol under various mobility models. We used random waypoint mobility models and reference point group mobility models with different speed and different number of source node to evaluate our protocol. The simulation result shows that our proposed protocol performance is lower in terms of energy consumption for random waypoint movement compare to the reference point group mobility model.

Keywords: Energy, gateway mode, mobility model, reverse route mechanism.

Performance Analysis of AODV-UI Routing Protocol With Energy Consumption Improvement Under Mobility Models in Hybrid Ad hoc Network

Abstract

In mobile ad hoc networks (MANETs), routing protocol plays the most important role. In the last decade, Ad hoc On-demand Distance Vector (AODV) routing protocol becomes the attention of focussed research on MANETs world wide. A lot of protocols had been proposed to improve and optimize AODV routing protocol to achieve the best in quest of reliable protocol. In this paper, we present some improvement suggestion to AODV routing protocol. Our proposed protocol, called AODV-UI, improved AODV in gateway interconnection, reverse route and in energy consumption. We also measure performance indicators for some metrics, such as energy, routing overhead, end-to-end delay, and packet delivery ratio. We performed our simulation scenarios with three mobility model with different maximum speed and sources in hybrid ad hoc network. The result shows that AODV-UI is more stable when it is used in random way point mobility model in any speed and number of sources.

What is Mobility Model?

April 14, 2011

Mobility models represent the movement of mobile users, and how their location, velocity and acceleration change over time. Such models are frequently used for simulation purposes when new communication or navigation techniques are investigated. Mobility management schemes for mobile communication systems make use of mobility models for predicting future user positions.

In the study of a new Mobile ad hoc network protocol, it is important to simulate the protocol and evaluate its protocol performance. Protocol simulation has several key parameters, including mobility model and communicating traffic pattern.[1] Mobility models characterize user movement patterns, i.e. the different behaviors of subscribers. Traffic models describe the condition of the mobile services.

For mobility modelling, the behaviour or activity of a user’s movement can be described using both analytical and simulation models. The input to analytical mobility models are simplifying assumptions regarding the movement behaviors of users. Such models can provide performance parameters for simple cases through mathematical calculations. In contrast, simulation models consider more detailed and realistic mobility scenarios. Such models can derive valuable solutions for more complex cases. Typical mobility models include
